The term "Genus Leiopelma" refers to the type of frog which is found only in New Zealand. There are several synonyms used for this genus like the New Zealand ground frog, leiopelmatid frogs, and Leiopelmatidae. They are known for their unique features such as primitive characteristics like lack of external eardrums, a globular body shape, and a short air passage. Leiopelmatids evolved before Jurassic times and have been known to exist more than 200 million years ago. They are a critical component of New Zealand's unique fauna, and their conservation is necessary to maintain the integrity of the ecosystem.
